With more than 5 million systems shipped to more than 75 manufacturers since 1996, DLP™ technology has a proven track record for outstanding dependability. The physical fatigue and failure mechanisms that govern mechanical behavior in macro- scale materials don’t seem to be as prominent in MEMS devices. Some of these devices have been cycled up and down times without failure. Approved for Public Release, Distribution Unlimited

EE42/100, Spring 2006Week 15, R. White21 Where Do We Go From Here? Nanoelectromechanical Systems (NEMS) NEMS are like MEMS, only one or more key enabling components or structures has a physical dimension of less than 1 micrometer in size and can be integrated with another dissimilar components. NEMS is the integration of sensors, actuators, electronics, photonics, energy, fluidics, chemistry, and biology into a meaningful system enabled by sub-micrometer science and engineering precision. We are now beginning the Age of NEMS. Approved for Public Release, Distribution Unlimited
